Since this an EM problem, the space is Minkowski, i.e., the line element in Cartesian is $ds^2 = -dt^2 + dx^2 + dy^2 + dz^2.$ To convert the spatial part of the Minkowsk line element $dx^2 + dy^2 + dz^2$ to spherical coordinates use the spherical coordinate transformation. Regarding the tensor, $B=0$ so you're only left with the projections of the $E(r)$ field on $(x,y,z).$ Either transform the tensor, or transform $E(r)$ to Cartesian coordinates. You can calculate $F_{\mu \nu}$ by either using the metric or the vector potentials in spherical coordinates. | |
